Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.
3. Heart
The heart is a roughly cone-shaped hollow muscular
organ. It is about 10 cm long and is about the size of the
owner's fist. It weighs about 225 g in women and is
heavier in men (about 310 g).
Position
The heart lies in the thoracic cavity in the mediastinum
between the lungs. It lies obliquely, a little more to the left
than the right, and presents a base above, and an apex
below. The apex is about 9 cm to the left of the midline at
the level of the 5th intercostal space, i.e. a little below the
nipple and slightly nearer the midline. The base extends to
the level of the 2nd rib.
4. Organs associated with the heart
Inferiorly — the apex rests on the
central tendon of the diaphragm.
Superiorly — the great blood vessels,
i.e. the aorta, superior vena cava,
pulmonary artery and pulmonary veins.
Posteriorly — the oesophagus, trachea,
left and right bronchus, descending
aorta, inferior vena cava and thoracic
vertebrae.
Laterally — the lungs — the left lung
overlaps the left side of the heart.
Anteriorly — the sternum, ribs and
intercostal muscles.
5. Structure
The heart is composed of three layers of
tissue:
pericardium, myocardium and endocardium.
Pericardium
• The pericardium is made up of two sacs. The
outer sac consists of fibrous tissue and the
inner of a continuous double layer of serous
membrane. The space between the parietal
and visceral pericardium is only a potential
space. In health the two layers are in close
association, with only the thin film of serous
fluid between them.
6. Myocardium
The myocardium is composed of specialised
cardiac muscle found only in the heart. It is
not under voluntary control but, like skeletal
muscle, cross-stripes are seen on microscopic
examination. Each fiber (cell) has a nucleus
and one or more branches. The ends of the
cells and their branches are in very close
contact with the ends and branches of
adjacent cells.
Endocardium
This forms the lining of the myocardium and
the heart valves. It is a thin, smooth,
glistening membrane which permits smooth
flow of blood inside the heart. It consists of
flattened epithelial cells, continuous with the
endothelium that lines the blood vessels.
7. Interior of the heart
The heart is divided into a right and left side by the
septum, a partition consisting of myocardium
covered by endocardium. After birth blood cannot
cross the septum from one side to the other. Each
side is divided by an atrioventricular valve into an
upper chamber, the atrium, and a lower chamber,
the ventricle. The atrioventricular valves are formed
by double folds of endocardium strengthened by a
little fibrous tissue. The right atrioventricular valve
(tricuspid valve) has three flaps or cusps and the left
atrioventricular valve (mitral valve) has two cusps.
8. The valves between the atria and
ventricles open and close passively
according to changes in pressure in the
chambers. They open when the pressure in
the atria is greater than that in the
ventricles. During ventricular systole
(contraction) the pressure in the ventricles
rises above that in the atria and the valves
snap shut preventing backward flow of
blood. The valves are prevented from
opening upwards into the atria by tendinous
cords, called chordae tendineae, which
extend from the inferior surface of the cusps
to little projections of myocardium covered
with endothelium, called papillary muscles.
9. Conducting system of the
heart
The heart has an intrinsic system whereby the
cardiac muscle is automatically stimulated to
contract without the need for a nerve supply from
the brain.
However, the intrinsic system can be stimulated or
depressed by nerve impulses initiated in the brain
and by circulating chemicals including hormones.
There are small groups of specialized
neuromuscular cells in the myocardium which
initiate and conduct impulses causing coordinated
and synchronized contraction of the heart muscle.
10. Sinoatrial node (SA node)
This small mass of specialised cells is in the wall of the right atrium near the
opening of the superior vena cava. The SA node is the 'pace-maker' of the heart
because it normally initiates impulses more rapidly than other groups of
neuromuscular cells.
Atrioventricular node (AV node)
This small mass of neuromuscular tissue is situated in the wall of the atrial
septum near the atrioventricular valves. Normally the AV node is stimulated by
impulses that sweep over the atrial myocardium. However, it too is capable of
initiating impulses that cause contraction but at a slower rate than the SA node.
11. Atrioventricular bundle (AV bundle or bundle of His)
This is a mass of specialised fibres that originate from the AV node. The AV
bundle crosses the fibrous ring that separates atria and ventricles then, at the
upper end of the ventricular septum, it divides into right and left bundle
branches. Within the ventricular myocardium the branches break up into fine
fibres, called the Purkinje fibres.AV bundle convey electrical impulses from the
AV node to the apex of the myocardium where the wave of ventricular
contraction begins, then sweeps upwards and outwards, pumping blood into the
pulmonary artery and the aorta.
12. Nerve supply to the heart
In addition to the intrinsic impulses generated within the conducting system described
above, the heart is influenced by autonomic nerves originating in the cardiovascular
centre in the medulla oblongata which reach it through the autonomic nervous system.
These consist of parasympathetic and sympathetic nerves and their actions are
antagonistic to one another.
The vagus nerves (parasympathetic) supply mainly the SA and AV nodes and atrial
muscle. Parasympathetic stimulation reduces the rate at which impulses are produced,
decreasing the rate and force of the heart beat.
The sympathetic nerves supply the SA and AV nodes and the myocardium of atria and
ventricles. Sympathetic stimulation increases the rate and force of the heart beat.
13. Factors affecting heart
rate
Autonomic nervous system.
Circulating chemicals. The hormones adrenaline and noradrenaline, secreted by
the adrenal medulla, have the same effect as sympathetic stimulation, i.e. they
increase the heart rate. Other hormones including thyroxine increase heart rate
by their metabolic effect. Some drugs, dissolved gases and electrolytes in the
blood may either increase or decrease the heart rate.
Position. When the person is upright, the heart rate is usually faster than when
lying down.
Exercise. Active muscles need more blood than resting muscles and this is
achieved by an increased heart rate and selective vasodilatation.
Emotional states. During excitement, fear or anxiety the heart rate is increased.
Other effects mediated by the sympathetic nervous system may be present.
Gender. The heart rate is faster in women than men.
Age. In babies and small children the heart rate is more rapid than in older
children and adults.
